It should be noted that the first direction and the second direction are two directions that are not parallel to each other, and in a specific example, the first direction and the second direction are perpendicular to each other, in combination with the direction shown in fig. 1, where the first direction is the X direction shown in the figure, and the second direction is the Y direction shown in the figure.

It can be understood that, the leveling device 100 of the present application can adjust the levelness of the leveling component 1 relative to the leveling plane in real time through the leveling component 2, and the leveling component 1 can automatically perform actions of leveling, vibrating, leveling and the like on the leveling plane through the cooperation of the first scraping plate 13, the vibrating component 12 and the second scraping plate 14 in the working process of the leveling component 1, so that the whole process does not need manual participation, the labor intensity of workers is reduced, the working efficiency is improved, and the leveling quality of the leveling device 100 is improved.

In the description of the present invention, "a plurality" means two or more unless otherwise specified.

The leveling device 100 in the present application is mainly used in the building decoration industry, and pours the mixed slurry onto the ground or other supporting surface, and levels the slurry with the first scraper 13, the second scraper 14 and the vibrating plate 121, and for the slurry, one of cement mortar, mixed mortar or lime mortar can be used, and there is no specific limitation here. The screed apparatus 100 of the present application is particularly suited for screeding concrete.

In some embodiments of the present invention, as shown in FIG. 2, the first screed 13, the screed assembly 12, and the second screed 14 are sequentially spaced apart along the direction of travel of the screed apparatus 100. That is, in the advancing direction of the leveling device 100, the first scraping plate 13 and the second scraping plate 14 are arranged on two opposite sides of the vibrating component 12 at intervals, and in the advancing process of the leveling device 100, the first scraping plate 13, the vibrating component 12 and the second scraping plate 14 can sequentially level the leveling plane, so that the leveling time is saved, the leveling quality is improved, and the first scraping plate 13, the vibrating component 12 and the second scraping plate 14 are arranged at intervals, so that if one structural member shakes or vibrates in the leveling process, the other two structural members cannot be influenced, and the leveling quality of the leveling device 100 is further improved.

For example: in the work of flattening subassembly 1 work, because of first scraper blade 13, shake flat subassembly 12 and the setting of second scraper blade 14 interval, if shake flat subassembly 12 and appear rocking or vibration at the in-process of flattening, the interval sets up and can guarantee to shake the vibration that flat subassembly 12 produced and can not transmit to first scraper blade 13 and second scraper blade 14 on, also can not influence first scraper blade 13 and second scraper blade 14 and carry out flattening work, further improves flattening quality of flattening device 100.

In a particular example, the direction of travel of screed 100 is the Y direction shown in fig. 1. Therefore, the first squeegee 13, the shake-and-leveling assembly 12, and the second squeegee 14 are sequentially provided at intervals in the Y direction.

Optionally, a first distance between the bottom of the first screed 13 and the planing surface is greater than a second distance between the bottom of the second screed 14 and the planing surface. As can be seen from fig. 2, in the moving direction of the leveling device 100, the first scraper 13 contacts the leveling surface first with respect to the second scraper 14, and by setting the distance between the first scraper 13, the second scraper 14 and the leveling surface, in the leveling process of the leveling device 100, the leveling surface can be initially leveled by the first scraper 13, and the leveling surface can be finely leveled by the second scraper 14, so as to improve the leveling quality of the leveling device 100.

Optionally, the third distance between the bottom of the vibratory leveling assembly 12 and the leveling surface is less than the first distance between the bottom of the first screed 13 and the leveling surface and greater than the second distance between the bottom of the second screed 14 and the leveling surface. That is, along the traveling direction of the leveling device 100, the distances between the bottom of the first scraping plate 13, the bottom of the vibrating component 12 and the bottom of the second scraping plate 14 and the leveling surface decrease in sequence, and during the process of moving the leveling device 100 along the traveling direction and leveling the leveling surface, the bottom of the first scraping plate 13 contacts the leveling surface and primarily levels the leveling surface, and then the leveling device 100 continues to move along the traveling direction, and the vibrating component 12 contacts the leveling surface leveled by the first scraping plate 13 and vibrationally discharges air bubbles inside the concrete on the leveling surface, so as to improve the compactness of the concrete working layer, and then the leveling device 100 continues to move along the traveling direction, and the bottom of the second scraping plate 14 contacts the leveling surface leveled by the vibrating component 12 and screeds the compacted concrete, thereby improving the leveling quality of the leveling device 100 and achieving high-precision leveling of the concrete.

In some embodiments of the invention, as shown in fig. 2, the first scraper 13 includes a bucket 131, and the bucket 131 is open to a side away from the screed assembly 12. Because of before leveling device 100 works, the concrete on the flattening surface is directly poured on the flattening surface usually, make the whole height of concrete on the flattening surface vary, and can appear that the concrete is more on the partial flattening surface, the condition of no concrete on the partial flattening surface, through setting up the pushing hopper 131, the pushing hopper 131 can push away the concrete on the flattening surface before flat subassembly 12 works of shaking, make the concrete on the flattening surface distribute evenly, so that follow-up flat subassembly 12's flattening work of shaking, and the pushing hopper 131 still can guarantee can not pile up on flat subassembly 12 at the in-process concrete that leveling device 100 gos forward, the life-span of extension flat subassembly 12 and the operating mass who improves flat subassembly 12 that shakes.

Alternatively, as shown in fig. 2, the push bucket 131 is spaced from the shake-out assembly 12 in the second direction. Because of flat subassembly 12 that shakes including the flat board 121 that shakes, the flat board 121 that shakes can produce the vibration at the in-process of work, can guarantee through shaking flat board 121 and shake flat subassembly 12 interval setting to shake and can not drive the in-process of vibration push away fill 131 and vibrate together, consequently make push away fill 131 stable in the in-process position of work, improve push away the work precision of fill 131, and then indirectly improve leveling device 100's flattening quality.

Optionally, the pushing bucket 131 includes a bottom plate vertically disposed along the Z-direction and a plurality of side plates disposed around the circumference of the bottom plate and extending obliquely toward a direction away from the shake-leveling assembly 12. The flaring that the area is greater than the bottom plate can be enclosed at the bottom plate opposite face to a plurality of curb plates that the slope set up after the installation is accomplished for increase the area of contact of pushing away hopper 131 and concrete, make pushing away hopper 131 can once only push away more concrete, improve and push away flat efficiency, and the curb plate that the slope set up still can play the effect of keeping out the concrete, guarantee that the concrete can not too much pile up on shaking flat subassembly 12.

In other examples, the first scraper 13 is not limited to the hopper 131, but the first scraper 13 may be a material pushing plate extending in the Z direction as long as it can push out uneven concrete, and the specific structure of the first scraper 13 is not particularly limited.

In some embodiments of the present invention, as shown in fig. 2, the second scraper 14 comprises a troweling plate 141, the troweling plate 141 extends in a curved manner toward a side away from the vibration leveling assembly 12, and the troweling plate 141 forms a troweling surface toward a side of the assembly Xiang Zhenping. The area of the troweling plate 141 that the bending extension set can increase the troweling surface, that is, the contact area between the troweling plate 141 and the leveling surface is increased, the troweling plate 141 can be ensured to scrape the compact concrete, so that the surface of the concrete layer after the air bubbles are discharged is more smooth, the high-precision leveling of the concrete is realized, and the leveling quality of the leveling device 100 is improved.

In a specific example, as shown in fig. 2, an end of the trowel plate 141 near the flat surface extends in a curved manner toward a side away from the vibration leveling assembly 12. That is to say, only one end of the troweling plate 141 forms a plastering surface, so that the material consumption during the production of the troweling plate 141 is reduced, the production cost of the troweling plate 141 is saved, and the plastering surface formed by the troweling plate 141 close to one end of the leveling surface can be used for scraping the compacted concrete.

Optionally, as shown in fig. 2, the troweling plate 141 is disposed spaced apart from the vibration leveling assembly 12 in the second direction. The beneficial effects of the troweling plate 141 and the vibration leveling component 12 that are disposed at an interval in the second direction can be referred to as the beneficial effects of the pushing bucket 131 and the vibration leveling component 12 that are disposed at an interval in the second direction, which is not described herein again.

Because of the dull and stereotyped 121 can produce the vibration at the in-process of work that shakes, dull and stereotyped 121 will shake is connected on mount 11 through hanging damper 122, guarantee to shake vibration transmission to mount 11 that dull and stereotyped 121 produced, it can not drive mount 11 at the in-process of vibration to shake dull and stereotyped 121 promptly together and vibrate also, guarantee mount 11 stable in position, and further guarantee to connect first scraper blade 13 and the second scraper blade 14 stable in position on mount 11, make first scraper blade 13 can effectively push away the uneven concrete of height and level, second scraper blade 14 can effectively strike off the concrete after closely knit.

Optionally, the vibration motor 123 is used for driving the vibration plate 121 to vibrate. Vibrating motor 123 self can produce high-frequency vibration to the drive shakes dull and stereotyped 121 vibration, makes to shake dull and stereotyped 121 and can improve the closely knit degree on concrete working layer with the inside bubble discharge of concrete on the whole plane.

Alternatively, as shown in fig. 3, the vibration motor 123 is connected to the vibration plate 121. The vibration motor 123 can drive the vibration plate 121 to vibrate in the process of generating high-frequency vibration, and the vibration plate 121 can also play a role in supporting the vibration motor 123, so that the relative position between the vibration motor 123 and the vibration plate 121 is stable.

Of course, in other examples, the driving member for driving the vibrating plate 121 to vibrate is not limited to the vibrating motor 123, and other vibrating driving members may be used.

Optionally, as shown in fig. 2 and fig. 3, the vibration leveling assembly 12 further includes two supporting members 124 symmetrically disposed, the two supporting members 124 are symmetrically disposed at two opposite sides of the vibration motor 123 and connected to the fixed frame 11, and the first scraper 13 and the second scraper 14 are respectively connected to two ends of the supporting members 124. The first scraper 13 and the second scraper 14 can be arranged on the fixing frame 11 at intervals.

Optionally, the support 124 is spaced apart from the vibrating plate 121. The vibration plate 121 is ensured not to drive the support member 124 to vibrate in the vibration process, that is, the first scraper 13 and the second scraper 14 are not driven to vibrate, and the structural stability of the first scraper 13 and the second scraper 14 is improved.

In some embodiments of the present invention, the first direction is a length direction of the adjustment frame 21, and the second direction is perpendicular to the first direction. Here, the first direction extends along the length direction of the adjustment bracket 21 such that the first direction is formed as an X direction shown in fig. 1, and the second direction is a direction perpendicular to the first direction such that the second direction is formed as a Y direction shown in fig. 1. Ensure leveling subassembly 2 and can adjust leveling subassembly 1 levelness in X side and can adjust leveling subassembly 1 levelness in Y side again, improve the levelness by the leveling plane after leveling subassembly 1 flattening to guarantee that the leveling plane after the flattening accords with predetermined quality requirement.

In some embodiments of the present invention, as shown in fig. 4, the first adjustment assembly 22 includes a first detection member 221, an adjustment lever 222, and a first driving member 223.

Alternatively, as shown in fig. 4, the first adjusting assemblies 22 include two first adjusting assemblies 22, two first adjusting assemblies 22 are spaced at two ends of the adjusting frame 21, and the two first adjusting assemblies 22 are used for adjusting the levelness of the leveling assembly 1 in the first direction.
